Everyone who follows the bulls of Pamplona assumes the same thing about Ganadería Núñez del Cuvillo. The surname Núñez is one of the most celebrated in Spanish bull breeding, attached to an entire genetic family, the encaste Núñez, created by the rancher Carlos Núñez Manso. So when the Núñez del Cuvillo bulls come up Cuesta de Santo Domingo, the natural conclusion is that Núñez blood is running the streets. It is not. The ranch eliminated the last of its Núñez genetics decades ago. What runs under that famous name today is a herd of Domecq and Osborne blood, bred on the Atlantic side of Cádiz province, with a brand that was designed in 1920 for red meat cattle rather than fighting bulls.
The distinction matters because bloodline is the single most useful thing a spectator or runner can know about an encierro. The eight ranches that supply Pamplona each July behave differently on the cobblestones, and those differences are genetic before they are anything else. Reading the Núñez del Cuvillo history correctly, as a Domecq and Osborne operation wearing a Núñez name, tells you far more about what its animals do between the corrals and the Plaza de Toros than the surname ever will. It also explains one of the stranger facts of the current decade: in 2026 this bloodline is running Pamplona again, but under a different name, while the parent ranch stays home.
This article draws on the ranch’s registry entry with the Agrupación Española de Ganaderos de Reses Bravas, the Spanish government’s fighting bull breed standard published in the Boletín Oficial del Estado, the encierro archives of sanfermin.com, and reporting in the Spanish press from La Vanguardia to Diario de Noticias. Nothing here rests on festival folklore.
A Brand Created in 1920 for Red Cattle, Not Fighting Bulls
The iron that marks every Núñez del Cuvillo bull is older than the ganadería itself by 62 years, and it was never meant for a fighting bull. Joaquín Núñez Manso, a Cádiz cattleman, created the brand in 1920 and asked his sister in law, María del Cuvillo D’Echecopas, to design it. The family business at the time was retinto cattle, the rust colored meat breed that still grazes across the province of Cádiz. The elegant hierro she drew spent its first six decades on animals destined for the butcher, not the bullring or the streets of Pamplona.
The family’s fame in fighting bull circles came through another branch. Joaquín Núñez Manso’s brother was Carlos Núñez Manso, who in the 1940s built one of the most influential bloodlines of the twentieth century, so distinct that Spanish breed authorities recognize it as its own encaste bearing his name. Bulls of Núñez blood carried the surname into the record books, and that is the association almost everyone still makes when they hear the name today.
Which is precisely the misconception. The man who founded the modern ganadería in 1982, Joaquín Núñez del Cuvillo, is the son of the brand’s creator and the nephew of the encaste’s creator. He inherited the name, the iron, and the family standing. The genetics he chose for his herd came from somewhere else entirely.
1982: The Herd Joaquín Núñez Actually Bought
The history of Ganadería Núñez del Cuvillo as a fighting bull operation begins in 1982, when Joaquín Núñez del Cuvillo purchased the herd of the Osborne Domecq brothers, stock that traced to José Luis Osborne and belonged to the Domecq encaste in its Osborne line. The registry entry of the Agrupación Española de Ganaderos de Reses Bravas records the founding purchase at 114 cows and 40 males.
Over the following decade he layered in more blood, nearly all of it from the same genetic family. In 1985 came animals from Belén Ordóñez, which did carry Carlos Núñez genetics. In 1988 he added cows and a sire from Sayalero y Bandrés, in 1989 stock from Atanasio Fernández, in 1990 a lot of 50 cows and two sires from Torrealta, and in 1992 animals from Juan Pedro Domecq Solís and the Marqués de Domecq.
Then he did something decisive. The Carlos Núñez and Atanasio Fernández lines were culled or absorbed until nothing functional remained of them. What survived the selection was Domecq through and through: today the herd is predominantly Marqués de Domecq and Osborne blood with contributions from Torrestrella, Jandilla, and Juan Pedro Domecq Solís. The one bloodline the ranch does not carry is the one its name advertises. In the space of a decade, the nephew of the man who created the encaste Núñez had built a ganadería with no Núñez in it.
What Domecq and Osborne Blood Looks Like in the Field
The ranch’s animals answer to the Juan Pedro Domecq encaste standard in its Osborne line, and Spain regulates what that means with unusual precision. Real Decreto 60/2001, the breed prototype published in the Boletín Oficial del Estado, describes the type: compact, harmonious animals with fine skin, a long dropped neck, a powerfully developed morrillo, short strong legs, and fine, well set horns. Coats run black, colorado, castaño, and tostado, with occasional jabonero and ensabanado animals appearing through old Vazqueña influence, plus accidental markings with names like listón, chorreado, salpicado, and ojo de perdiz. A Núñez del Cuvillo string in the corrals is usually a study in that range, four or five dark animals alongside a chestnut or a light one.
The herd grazes where it always has, on the Atlantic side of Cádiz province. The home farms are El Grullo and El Gallarín in Vejer de la Frontera, with El Lanchar in Conil de la Frontera and Los Arenalejos in Medina Sidonia. The ranch runs under a divisa of green, white, and red, and holds entry number 448 in the breeders’ association registry. It is a family operation in the most literal sense, still directed by its founder more than four decades after the founding purchase.
Twelve Runs Through Pamplona Since 1995
Núñez del Cuvillo bulls have made the 848.6 meter journey from the Corrales de Santo Domingo to the Plaza de Toros twelve times: 1995, 2000, 2004, 2008, 2009, 2011, 2016, 2017, 2018, 2019, 2022, and 2023. The pattern across those mornings is consistent with the Domecq genetics: fast, mobile animals that hold a strong gallop up Santo Domingo and produce quick encierros. The 2009 run went in 2 minutes 21 seconds, the 2011 run in 2 minutes 20 seconds without a single goring, and the 2023 run in 2 minutes 21 seconds, clean again. When a bull gets separated from the herd, though, these animals punish. The 2017 encierro saw the herd break apart at speed and gore two runners, and in 2019 a bull caught a runner in the leg on Santo Domingo. Across the ranch’s first ten appearances, its animals gored eleven people.
The date that belongs in any account of this ganadería is July 7, 2022. After two consecutive years of pandemic cancellation, Pamplona restarted its signature tradition, and the animals chosen to open that first fiesta back were Núñez del Cuvillo’s. They delivered a 2 minute 35 second run without a goring. The ranch returned in 2023 for another fast, clean morning, and has not been back since.
The Bloodline’s Next Chapter Runs Under Another Name
The absence is not an ending. In 2020 Álvaro Núñez Benjumea, son of Joaquín Núñez del Cuvillo, took roughly 140 head of his father’s stock and founded his own ganadería on the El Cuarto farm in Los Barrios, Cádiz, refreshing the base with animals from Garcigrande and from the ganadería of Alejandro Talavante. The brand won approval in 2021. On July 9, 2025, the young ranch’s bulls ran Pamplona for the first time, and the lineup announced for the 2026 Sanfermines includes them again, alongside Fuente Ymbro, Cebada Gago, Victoriano del Río, José Escolar, La Palmosilla, Miura, and Jandilla.
Which completes a neat historical circle. A name that began on meat cattle in 1920 became one of the most recognized in the fighting bull world without ever carrying the blood it evokes, and the genetics that actually built its reputation are now running the streets of Pamplona under a third name. Anyone standing at the fences this July watching the Álvaro Núñez bulls is watching the Núñez del Cuvillo herd’s direct descendants, one more generation of a Cádiz family that has now sent two ganaderías, and zero drops of Núñez blood, up Calle Estafeta.
Frequently Asked Questions
Where is the Núñez del Cuvillo bull ranch located?
The ranch operates on four farms in the province of Cádiz, in southern Spain: El Grullo and El Gallarín in Vejer de la Frontera, El Lanchar in Conil de la Frontera, and Los Arenalejos in Medina Sidonia. The area’s coastal pasture has supported the family’s cattle since the early twentieth century, when it still raised retinto meat cattle under the same brand the fighting bulls wear today.
What bloodline are Núñez del Cuvillo bulls?
Despite the surname, they carry no Núñez encaste blood. The herd belongs to the Juan Pedro Domecq encaste in its Osborne line, built from the 1982 purchase of the Osborne Domecq herd and later additions of Marqués de Domecq, Torrealta, Torrestrella, Jandilla, and Juan Pedro Domecq Solís stock. The Carlos Núñez genetics that entered briefly in 1985 through Belén Ordóñez were eliminated from the breeding program.
When did Núñez del Cuvillo last run in Pamplona?
July 11, 2023. That morning’s encierro took 2 minutes 21 seconds and produced no gorings. It was the ranch’s twelfth appearance since its 1995 debut, and it followed a piece of history the year before, when its bulls opened the 2022 Sanfermines, the first festival after two years of pandemic cancellation.
Is Núñez del Cuvillo running in San Fermín 2026?
No. The eight ranches announced for 2026 are Fuente Ymbro, Cebada Gago, Victoriano del Río, Álvaro Núñez, José Escolar, La Palmosilla, Miura, and Jandilla. The bloodline is represented all the same: Álvaro Núñez is the ganadería founded in 2020 by the son of Joaquín Núñez del Cuvillo with about 140 head of the family herd, and it debuted on Pamplona’s streets on July 9, 2025.
